Do you know what the rating is on the air conditioner, guess if its small enough a eu2000, but most seem to need the 3000. Also a hard start option on the air conditioner may help, if you do a search, this topic was done earlier today, it think/

Anything less than 2000 Watts will not handle most airconditioners. In most cases a Yamaha 2400 will do the job.
The Yamaha 2800 will do the job as will either the Honda or the Yamaha 3000.
There are Kipor and Champion genorators that will also work.

13,500 btu/hr air conditioner is more tricky. A high efficiency A/C might be OK on 2400 watt. A standard full-height model might be OK on 3KW, or might be trouble. A low profile 13,500 should be on a 3600-4000, because that low profile comes at the cost of making a smaller A/C work harder.

A lot depends on WHAT ELSE in the RV will load the generator. If the load was truly only A/C, then a 2.4 KW (continuous) genset will run any RV air conditioner, because all are sized for a 20 amp circuit.

I was just reading a blog about the "portable" A/C units that draw about half the power of the rooftop models....in which case, all but the smallest of gensets might work. It depends again, on what system you have, or plan to get.

We run our one AC without any problem with a Honda EU2000. We can also charge our batteries, run the heater, microwave, TV and anything in the 5er, just not all at the same time. It's fairly quiet and light weight.

After doing a lot of shopping around, we got a great price on our Honda generator at Wise Sales

Check them out and give the experts a call and find out which generator is best for you. 1-800-916-9473.

It doesn't matter where you go in life.........it's who you have beside you

If you are going to power an AC might as well do it right and get the Honda EU3000 or the Yamaha EF3000ise. If you want to save some money then drop down to the Yamaha 2400. I think the Honda 2000 will be working too hard and in the case of some a/c it wont work at all. Its not designed to run an ac. I wouldnt wasted money buying a cheap generator thats so noisy it defeats the purpose of going camping.
